Caspar’s Hollow is the first installment of a trilogy. Caspar and his three brothers escape from their drunken father into the forest behind their house. They come upon a hollow filled with mythical creatures who befriend and take the brothers into their community. The presence of humans stirs discontentment with some of the Hollow creatures and sparks attacks from the opposing community from the nearby mountain. Caspar’s best friend, a warrior fairy, and the elvish king of the community must find a way to get the brothers back to safety without risking the onset of war.
